Those who choose to drive on Montana roads should make sure that they are not sleep deprived or under the influence of sleep medication. According to a Consumer Reports survey, roughly 20% of respondents who took prescription sleep aids did so less than seven hours before driving a vehicle. The directions say that an individual should wait at least seven hours before driving to avoid doing so while groggy.
Individuals who drive while sleep deprived could experience the same effects as those who drive while under the influence of alcohol. Driving after being awake for 24 consecutive hours is the same as operating a motor vehicle with a blood alcohol content of .10%, which is above the legal limit of .08%. A study conducted by AAA in 2018 found that 9.5% of crashes are caused by drowsy drivers.
